Hattner, author of “Gut Insight,” said intermittent fasting may burn fat, but it could also affect your mood, especially in women.

She says if you want to try it, test it out when you’re not working, taking care of kids or operating heavy machinery.

“I certainly wouldn’t want to be driving a car,” said Hattner.

The plan is based on work done by scientists at the Salk Institute. The research involved mice, but the co-authors analyzed how the diet worked in a few thousand web followers. And while the diet has not been subjected to clinical testing, Moore said it works and he’s never felt better.

Moore said the research shows how the eight-hour diet works on a cellular level, by triggering a person’s body to selectively burn fat for energy.
